When an object falls freely, an acceleration is produced to gravitational force and is called acceleration due to gravity and is denoted by the letter g F = mg but, F = DM m DM m mg = g = DM d d d 1 Black has more mass/ weight According to Newton s I Law of Motion Statement- 16 Any points 17 External parasite Skin diseases; worms affect stomach and intestine; Flukes damage liver 18 (a) Definition of each term Bos indicus 19 (a) Physical change reversible change, chemical composition do not change, no new substance is formed Chemical change - irreversible change, chemical composition changes, new substance is formed.

5 Any two differences example Tearing a paper physical changes Burning a match stick chemical change (i) Metals are malleable and good conductors of heat 0 (a) Activity diagram 1.6 Metals are ductile and good conductors of electricity (i) Evaporation is a surface phenomenon while boiling is a bulk phenomenon. Evaporation takes place at all temperatures while boiling takes place at a particular temperature 1 (a) Correct fig No. 6.4 (i) of NCERT Text Book Class IX with four parts lablled correctly. Difference Parenchyma (1) Inter cellular spaces are present () Cells are elongated (a) We =6xWm = 6x1.67 =10.0 N Mass on earth same i.e 1 kg F=.7 x10 N Force of earth on sun will be same According to Newton s III Law of Motion. Collenchyma (1) Very little Inter cellular spaces. () Cells may be circular, oval or polygonal. An object moving downward will continue to move downwards unless acted upon by an unbalanced force. If you make an effort to supply such a force in an attempt to suddenly alter the direction of your motion, then you are creating a greater velocity change than if (in the same amount of time as the stopping of you and the elevator), then you would experience a greater acceleration, a greater net force. According to Newton s I Law of motion. Same force acting on the rope, on both the ends. Newton s III Law of motion. According to the law of inetia. 4 (a) In mixed cropping two or more crops are grown simultaneously. For eg wheat gram (or any other correct e.g) Inter - cropping - two or more crops are grown simultaneously on the same field in a definite pattern. For eg, soyabean +maize (or any other correct e-g) In crop rotation different crops are grown on a piece of land in a pre-planned succession. Depending upon duration of crop rotation is done for different crop combination. Inter- Cropping - crops are selected such that their nutrient requirements are different. This ensures maximum utilization of the nutrients supplied and prevents pests and diseases from spreading to all plants - thus better returns. Crop - rotation - Availability of moisture and irrigation facilities Two or more crops can be grown in a year with good harvest SECTION - B 6(d) (d) anthracene. 4 A and D Properties :- (i) A colloid is a heterogeneous mixture Shows tyndal effect.
